Your network consists of a single Active Directory domain. The domain contains a server named Server1 that runs Windows Server 2008 R2. All client computers run Windows 7. All computers are members of the Active Directory domain.
You assign the Secure Server (Require Security) IPsec policy to Server1 by using a Group Policy object (GPO).
Users report that they fail to connect to Server1.
You need to ensure that users can connect to Server1. All connections to Server1 must be encrypted.
What should you do?

Your network contains one Active Directory domain. You have a member server that runs Windows Server 2008 R2.
You need to immediately disable all incoming connections to the server.
What should you do?

Your network uses IPv4.
You install a server that runs Windows Server 2008 R2 at a branch office. The server is configured with two network interfaces.
You need to configure routing on the server at the branch office. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You have a DHCP server that runs Windows Server 2008 R2. You restore the DHCP database by using a recent backup. You need to prevent DHCP clients from receiving IP addresses that are currently in use on the network.
What should you do?

You have a DHCP server that runs Windows Server 2008 R2. The DHCP server has two network connections named LAN1 and LAN2.
You need to prevent the DHCP server from responding to DHCP client requests on LAN2. The server must continue to respond to non-DHCP client requests on LAN2.
What should you do?

You have a DHCP server that runs Windows Server 2008 R2.
You need to reduce the size of the DHCP database.
What should you do?

You have a DHCP server named Server1 and an application server named Server2. Both servers run Windows Server 2008 R2. The DHCP server contains one scope. You need to ensure that Server2 always receives the same IP address. Server2 must receive its DNS settings and its WINS settings from DHCP.
What should you do?

Your company has four DNS servers that run Windows Server 2008 R2. Each server has a static IP address.
You need to prevent DHCP from assigning the addresses of the DNS servers to DHCP clients.
What should you do?

You have a Windows Server 2008 R2 computer that has an IP address of 172.16.45.9/21.
The server is configured to use IPv6 addressing.
You need to test IPv6 communication to a server that has an IP address of 172.16.40.18/21.
What should you do from a command prompt?

Your company has computers in multiple locations that use IPv4 and IPv6. Each location is protected by a firewall that performs symmetric NAT.
You need to allow peer-to-peer communication between all locations.
